    The number of FixedLocator locations (13), usually from a call to set_ticks, 
    does not match the number of ticklabels (12).
    

    最近使用时序预测模型对风机的各项参数做了预测,最后想可视化这些参数各自的预测误差,但是在使用matplotlib绘制雷达图时,出现了如上所述问题。

    解决方案:

    • 保证绘图时featurevalues数量一致:
      函数内代码第三行后加上feature=np.concatenate((feature,[feature[0]]))

    过程
    起初,我的代码如下:

    def radarplot(values, feature):
        # 设置每个数据点的显示位置,在雷达图上用角度表示
        angles=np.linspace(0, 2*np.pi,len(values), endpoint=False)
        # 拼接数据首尾,使图形中线条封闭
        values=np.concatenate((values,[values[0]]))
        angles=np.concatenate((angles,[angles[0]]))
        fig=plt.figure()
        ax = fig.add_subplot(111, polar=True)
        ax.plot(angles, values, 'o-', linewidth=2)
        ax.fill(angles, values, alpha=0.25) 
        ax.set_thetagrids(angles * 180/np.pi, feature)
        ax.grid(True)
        
    test_rmse_each = np.sqrt(np.mean(test_err.values**2, axis=0))
    #print(test_rmse_each,test_err.columns)
    radarplot(test_rmse_each, test_err.columns)
    

    运行结果虽然能显示出雷达图,但是会有错误提示,且没有显示各个角度对应的属性名称。在这里插入图片描述
    报错定位在这一行
    在这里插入图片描述
    最开始,根据报错提示,感觉应该是一开始设定的标签数量(radarplot函数内第一行:angles=np.linspace(0, 2*np.pi,len(values), endpoint=False))和后面绘图时输入值的数量(radarplot函数内第八行:ax.set_thetagrids(angles * 180/np.pi, feature))不匹配了。注意函数里第一行,我们在设置角度时,根据value的个数来设置的,但是后面的np.concatenate函数却又进行了一次首尾相连,相当于此时的value数值是在原来的基础上又加了1。应该是此处导致了报错。所以我们要解决的就是这个问题。
    在网上搜索后发现,matplotlib新版本(应该是2020之后)不需要再进行np.concatenate了,于是把函数内第二、三行注释掉。此时,代码就可以成功运行,没有报错,而且各个角度上显示的也是属性,而不是角度,但是雷达图不闭合。
    在这里插入图片描述
    要想雷达图闭合就需要进行首尾相连的操作,但是网上搜到的方法都是说注释掉np.concatenate行,显然这种解决方法不能帮我们得到一个好看的闭合的雷达图。转念一想,上面出错是因为feature数量和np.concatenate后的value数量不一致了,那我们把feature数量也加一不就可以了嘛。于是,按照类似的操作,在函数内代码第三行后加上feature=np.concatenate((feature,[feature[0]])) ,再运行代码,完美~

    问题根本:这通常是因为运行NPM安装后环境发生了变化。

    运行“NPM重建节点SASS——强制”来为当前环境构建绑定。

    也就是说你的node.js版本发生了变化

    解决办法:

    • 按照提示执行 npm rebuild node-sass 命令

    • 尚若还不行,则:先运行npm install node-sass命令
      再运行 npm rebuild node-sass 命令

      启动项目
